I appreciate the effort, but the video doesn't look very interesting. There is nothing in the way of scenery changes or anything similar to this. The enemies are also generic metallic figures that fire in predictable patterns. I suggest working with camera angles (look at Ikaruga's first stage or if you wanna keep it 2D, look at soldier blade's graphic changes), and adding much more variety in the enemies and the weapons (Override for the turbografx-16 is a good example of that).
